Pie Chart

A Pie Chart can have this appearance:

You define this appearance - or its alternatives - on the 'Appearance' page of the element 'Properties' dialog, after having set the 'Type' field on the 'Source' page to Pie. Each change in setting is immediately illustrated by an example Chart on the 'Appearance' page.

Category

Click on the drop down arrow and select the Pie Chart category:

  • 3D Chart - the Chart displays as a 3-D disc tilted away from you
  • Doughnut - the Chart displays as a 2-D ring
  • Doughnut 3D - the Chart displays as a 3-D ring with a rectangular profile
  • Torus 3D - the Chart displays as a 3-D ring with an elliptical profile
  • Pie - the Chart displays as a 2-D disc (the default, as illustrated above)

Label Position

You can show the meaning and value of each segment of the Chart as a label (see Show Data Labels); if you want to do this, you can specify where on the Chart the label will display.

Click on the drop down arrow and select the position in which to display the labels relative to the segments:

  • Center - the label is shown in the middle of the segment
  • Inside End - the label is shown inside the rim of the segment,
  • Inside Base - the label is shown closer to the point of the segment
  • Outside End - the label is shown outside the rim of the segment and linked to it by a line (the default, as shown for the 'Exploded' field)

Show Data Labels

Select the checkbox to display a label against each segment of the Pie Chart.

  • If the 'Show Index in Labels' checkbox is selected, only the index numbers (1, 2, 3...) display in the labels, keyed to the legend (see Display Legend)
  • If the 'Show Index in Labels' checkbox is not selected, the property name and percentage (such as Approved, 12.9%) display in the labels

Gradient

Click on the drop down arrow and select the direction of the color gradient across the Chart:

  • Solid Color (no color gradient)
  • Diagonal Left (the default, as shown above; color fades from right to left)
  • Diagonal Right (color fades from left to right)
  • Radial (color fades from edges to center)
  • Bevel (dark rim and color fading from the bottom to the top)

The Torus 3D category of Chart relies on a specific color gradient to create the effect of the Torus, therefore changes in the Gradient settings have no effect on Charts of this type.

Hole Size

This field is available for the Doughnut and Doughnut 3D categories of the Pie Chart.

Click on the slider and drag it to expand or contract the size of the hole in the middle of the Chart. The default (and the fixed size of the Torus 3D category) is 50%.

If you drag the hole size to 0%, the Chart is effectively a Pie Chart or 3D Chart.

Show Index in Labels

If you are displaying the meaning and value of each segment, you can display a legend providing this information (see Display Legend) and have a simple index to the legend as a label against each segment.

Select the checkbox to display the index (1, 2, 3...) as the label text

Clear the checkbox to display more complete information in the label.

Exploded

Select the checkbox to pull each segment of the Chart out away from the other segments, with the 'first ' segment separated out even further.

Fit Diagram Area

As you re-size your Chart element, the Chart width and height normally change with the element but stay in proportion.

Leave this checkbox unselected to maintain this behavior.

Select this checkbox to expand the Chart to fit the element space, even if the Chart has to elongate disproportionately up and down or sideways.

Display Legend

You can select to show the meaning and value of the Chart segments on the Chart itself, as labels, or you can display some or all of this information as a legend to the right of the diagram.

Select this checkbox to display a legend for the Chart.

Deselect the checkbox to hide the legend.

Position Dial

For the 3D Chart and Doughnut 3D categories:

  • The small top (up) arrow swings the Chart toward horizontal, so you are increasing the side view; the extreme is to show the front edge of the Chart
  • The small bottom (down) arrow swings the Chart towards vertical, so you are increasing the top view; the extreme is to show a Pie Chart or Doughnut Chart

For all categories of Pie Chart:

  • The rotating arrow at the center returns the Chart to its default perspective
  • The left- pointing arrow rotates the Chart by 24-degree increments anti-clockwise
  • The right -pointing arrow rotates the Chart in 24-degree increments clockwise
